Abstract (en)
[origin: EP4163048A1] A workpiece processing method includes performing additive manufacturing for a first region (460) of a workpiece (400); and performing additive manufacturing for a second region (470) of the workpiece (400), the second region (470) being smaller in width than the first region (460). The performing additive manufacturing for the first region (460) includes positioning an additive-manufacturing head (21) and the workpiece (400) relative to each other so as to make a distance between the workpiece (400) and a laser beam emitter in the additive-manufacturing head (21) equal to a first distance (La). The performing additive manufacturing for the second region (470) includes positioning the additive-manufacturing head (21) and the workpiece (400) relative to each other so as to make the distance between the workpiece (400) and the laser beam emitter in the additive-manufacturing head (21) equal to a second distance (Lb) that is smaller than the first distance (La).
